I'd suggest two things. Fix permissions and remove your user cache. This can be done with Applejack or Onyx.
I downloaded Applejack and whatever I did it seems to be fine now. Only problem is that Ive the same problem now with Adobe Illustrator....so I guess over to that forum.
I found a solution.
Got to your program icon for Acrobat - and right click - open package contents -
Then go to the plug-ins folder and delete the Updater folder -
It should stop crashing from there one.
